Promoting green-building development in sustainable development strategy: A multi-player quantum game approach

Sustainable development has become the development goal of all countries worldwide. Promoting green buildings in sustainable development is important to promote environment-friendly development. Considering this, we used the multi-player quantum game method to analyze the interest relationship between the developer, general construction contractor, and building materials supplier for the development of green-building and discussed the influence of the three on the game system. Furthermore, this study proposes a novel three-person quantum game model, discusses the optimal strategy selection process of the three parties with and without considering the entanglement, and uses a practical engineering case to prove the effectiveness of the proposed method. Without considering the entanglement of states, developers have the lowest willingness to invest in green-building, that is, the minimum investment of 28 million. When entanglement of states is considered and the initial state is |psi ini) = J|000), developers have the highest intention to invest in green buildings, that is, 56 million. Compared with the initial state of |psi ini) = J|111) when entanglement of states is not considered and entanglement of states is considered, developers'intention to invest in green-building shows an upward trend. The results show that entanglement can effectively prevent betrayal in the process of green-building construc-tion. Finally, according to the meaning of quantum entanglement and quantum strategy, an "entanglement treaty" is constructed, aiming at reducing the occurrence of treachery and providing an important guarantee for encouraging green-building participants to actively participate in green-building development. This study pro-vides a decision reference for promoting green-building construction. The proposed method is also applicable in other fields.
